Patrick Stump is a dad

Rocker Patrick Stump is a first-time dad.

Just a month after announcing his wife Elisa Yao was pregnant with their first child, the Fall Out Boy star recently welcomed a baby boy.

Stump chose a unique way to share the news, asking comedienne Ellen DeGeneres to take to Twitter.com on Wednesday (15Oct14) with their baby announcement.

She posted a photo of the newborn along with the caption, "It's a boy! Actually, it's a @FallOutBoy. Congrats @PatrickStump and welcome baby Declan! See y'all in 2 weeks!"

Stump and Yao wed in October, 2012.
